TO AMEND THE LAW CONCERNING MUNICIPAL REGULATIONS; AND TO PROHIBIT CERTAIN RESTRICTIONS ON THE REGULATION OF ACCESSORY DWELLING UNITS.
HB 1503 prohibits local governments from imposing certain restrictions on accessory dwelling units (ADUs), such as secondary housing units on residential property. The bill specifically blocks municipalities from banning ADUs entirely or setting fees exceeding $250 for their approval. It also invalidates local rules conflicting with this provision and requires water/sewer system approvals or health department clearance for ADU construction. This law directly affects homeowners, developers, and city planners by expanding opportunities to build small secondary homes on existing residential lots.
